I built a low-level systems interview prep platform - looking for feedback

reddit SideProject · 原文链接 ↗ · 46 分

I've been working on a side project called ForjaCero - a SaaS platform for System Software Engineering interview preparation.. The idea is pretty simple: I wanted to build something for systems/low-level engineering interviews that focuses not just on getting the right answer, but on practicing how you actually approach a problem in an interview . For example, instead of immediately jumping into an editor, you get a whiteboard where you can work through your approach first. There's also a 30-minute timer, with hints becoming available progressively if you get stuck. What's worki

痛点：系统底层（C/C++/Rust）工程师面试准备缺乏能练习“解题思路与过程”的工具，主流平台只覆盖算法刷题和结果判定。

目标用户：准备系统软件/底层岗位面试的候选人（应届生、转岗工程师、HFT/嵌入式/操作系统/数据库方向求职者）

证据：I wanted to build something for systems/low-level engineering interviews that focuses not just on getting the right answer, but on practicing how you actually approach a problem in an interview. / Thinking through a grading system that can evaluate how someone solves problems, rather than just whether their final answer is correct

变现：订阅制（月付/年付）解锁完整题库与提示；单次付费的模拟面试（human mock interview）抽成；面向高校/训练营的团队授权。

MVP：2周内只做核心闭环：30-50道 C/C++/Rust 系统题 + 白板画图 + 30分钟倒计时 + 分层渐进提示 + 参考解。代码执行用 Judge0/Piston 等现成沙箱 API 接入，暂不做 AI 面试官和自动评分，先验证有人愿意为“过程练习”付费。

竞品：LeetCode、AlgoExpert、Exponent、interviewing.io、Educative (Grokking)、Pramp、HackerRank、Codility、System Design Primer

摘要：独立开发者在 r/SideProject 发布 ForjaCero，一个面向 C/C++/Rust 系统底层面试准备的 SaaS，已有白板、30分钟计时、3层渐进提示、系统设计题和基础复习模块，正在开发代码执行环境和 AI 面试官。帖子定位清晰但仅是求反馈，未披露任何收入数据或用户付费意愿，也没有他人附和，需求验证薄弱；不过底层系统面试这一细分赛道相较通用算法刷题平台竞争更少，2周内可做出白板+题库+提示的轻量 MVP 验证。
